Location Privacy Preservation Mechanism for Location-Based Service With Incomplete Location Data

Location Positioning and Privacy Preservation Methods in Location-based Service

Location-based services (LBS) become more feature-rich and versatile due to the explosion of mobile devices and the advances of positioning technologies. However, revealing personal private locations to potentially un-trusted LBS server and others may raise serious privacy concerns if these locations are not protected adequately. In this paper, we present a survey of existing methods dealing wi...

Location Data Privacy Preservation in Mobile Networks

Uncontrolled variety of location based service (LBS) applications in mobile networks led to the loss of individual user location data privacy. To preserve privacy in mobile networks data randomization and anonymization must be used because of location data uncertainty. By data randomization additional random data is added to the original location data, desensitizing the precise information cont...

Survey of Location privacy in Location Based Service Proposal

Location Depersonalization for Location Privacy Protection in Location-Based Services

A spatial region with K different footprints indicates that it has been visited by K different people. An adversary may be able to identify all these users, but will not know who was there at what time. This observation gives us a new direction to investigate location depersonalization in location-based services (LBSs). We propose to leverage users’ historical location samples, each being a foo...

Privacy-Preserving Location-Based Service Scheme for Mobile Sensing Data †

With the wide use of mobile sensing application, more and more location-embedded data are collected and stored in mobile clouds, such as iCloud, Samsung cloud, etc. Using these data, the cloud service provider (CSP) can provide location-based service (LBS) for users. However, the mobile cloud is untrustworthy. The privacy concerns force the sensitive locations to be stored on the mobile cloud i...
